APPARATUS FOR PROTECTING FROM TERMITES nmLnmGs i Absalom n. Purifoy, Mobile, Am. Application August s,- 1936, serial No. 94,076'.

' s claims, (ci. 1s-124) This invention relatesto apparatus for protecting buildings from termites' and has for an object to provide apparatus including wicks extending around the entire foundation of the 5 building, both inside and outside, and communicating with tanks of poisonous or other fluid such as oil, which is distributed throughout the entire length of the wicks by capillary attraction whereby an eiective barrier against entrance of the termites to the building is eiected.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fullydescribed and claimed', it being understood that various mqdications may be resorted to Within the scope'of the appended claims without departing from the spirit or sacrificing any'of the advantages of the invention.

In the accompanying drawing forming partof 20 this specication,

Figure 1 is a sectional view of a portionof a building equipped with protective apparatus constructed in accordance with the invention.

Figure 2 is a cross sectional view taken on the line 2-2 of Figure l.

Figure 3 is a detail cross sectional view of one of the shields showing the wire clamps for attaching the Wicks thereto.

Referring now to the drawing in which like characters of reference designate similar'parts in the various views, i designates the foundation', II the sill, and I2 the floorbeams of a conventional building. The apparatus comprising the subject matter of this invention comprises substantially U-shaped shields in the form of troughs or gutters I3 and I4 which are disposed on the foundation below the sill inside and outside of thefoundation as illustrated. The shields are vsecured to the foundation and to each other by tie rods AI5 passed through the foundationand headed' up within the' shield as shown at .16, At intervals around the entire foundation pipes-I1 are passed through the foundation and open at the ends into the shields I3 and I 4.

A pair of wicks I8 and I9 are disposedin'the inner and outer shields and extend entirely around the building,.as best shown in Figure 2.

At intervals the wicks are secured to the shields by wire clamps 2l) which are secured centrally to the shields. The free ends of thel wires are bent over the wicks to embrace the wicks, as

shown in Figure 2.

At intervals the inner and outer wicks are connecte by -wicks 2| which are disposed in the 55 beforementioned pipes I1, Preferably at the .iunctures of the inner ends -of the transverse Wicks with the inner wick I9, wicks 22 are connected to the inner wicks and hang down into respective containers 23., The containers are supported upon the foundation, or otherwise se- 5 cured in position and are of sufiicient capacity to contain a supply of poisonous liquid 24, oil, or other liquid which is distributed throughout the entire length of the inner wicks, the outer wick, and transverse wicks by capillary attracl0 tion. Each container is equipped with a filling nozzle 25 for replenishing the supply of'liquid at frequent intervals. As best shown in Figure 3, the outer shield .is provided at the top with a downwardlyinclined ange 26 which overhangs an upstanding ange 21 on the bottom of the shield and prevents entrance of rainand foreign matter to the shield. In practice termites seeking entrance to the woodwork of the building will encounter the wicks which forman effective barrier below the sills of the building to prevent the termites-gaining access to the building between the foundation and the sills or floor beams while at the same time if poisonous liquid is used the termites will be destroyed while attempting to pass over the wicks.

From the above description it is thought that the construction and operation of the invention will be fully understood without further expla- 30 nation.

What is claimed is: l Q

1. A capillary apparatus for protecting buildings from termites comprising inner and outer shields extending completely around the foundation of the building, wicks equal in length to the shields and secured within the shields, tubes connecting the shields and passing through the foundation, fluid containing tanks near the inner ends of the tubes, and wicks in the tubes connecting the ilrst named wicks together and extending into the fluid in the tanks whereby the fluid is distributed throughout the entire length of all of the wicks by capillary attraction.

2. In-apparatusfor protecting a building Yfrom termites, a shield adapted toextend completely around the building near the floor line, means on the shield for preventing the entry of rain and foreign matter, a wickin the shield of thev same length as the shield, wire clamps securing the wick to the shield, a tube connected' to the shield and adapted to pass into the building, and a liquid container near the inner end of the tube,

a portion of said wick extending through the tube and being immersed in the liquid in the tank whereby the liquid is distributed throughout the entire length or the wick by capillary attraction.

3. In apparatus for protecting a building from termites, inner and outer shields secured to the building foundation, tubes passing through the foundation and connecting both shields, wicks in both shields extending completely around the foundation, wicks in the tubes connecting both the rst named wicks together, liquid'containers in the building, and wicks connected to the inner wick and immersed in the liquid in the container whereby the liquid is distributedl throughout the entire length oi all of the wicks by capillary attraction. v
